Before a walk goes in, the permit question has to be settled with the local office. In Appleton that's the City of Appleton Inspection Division, which handles city building permits at 100 North Appleton Street and takes calls at (920) 832-6411. Whether your walkway needs a permit is up to the division, so we check with them before work starts, and when one is needed, we pull it ourselves and keep the paperwork in order.
Wisconsin also grants a Dwelling Contractor credential to contracting businesses that obtain building permits for one- and two-family homes. It's held by the owner, a partner or the chief executive of the business, and the state requires either a bond of at least $25,000 or general liability insurance of at least $250,000 per occurrence. You're entitled to ask any contractor who at the company holds it.
We're based in Appleton and do the same work in the cities around it, including Grand Chute and Neenah. Many of the homes we work on here are older brick and stone houses, and on those I care as much that the walk suits the house as that it's solid underfoot.
